Question

what is the mass of 10 cc of water at 4 degree c​

Answer 1

Answer:

3.0 ×10−23 mL

Given density =1×103 kgm−3=1 gm−3

Molar mass of water =18 gm/mole

No. of moles in 1 gm =1/18=0.55 moles

18 gm contain molecules of H2O = 6.022×1023

1 gm contain molecules of H2O = 186.022×1023=0.33×1023

Volume occupied by 1 molecule of water is =0.33×10231=2.99×10−23
